I've got this error now twice in a row: The program 'CoherentUI_Host' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAccess (attempt to access private resource denied)'. (Details: serial 240526 error_code 10 request_code 130 minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Both times I've misclicked while dragging up a selection box and both times PA hung in box-select mode without accepting any other input (clicking, ESC, smashing head on keyboard, etc). Keybindings from the window manager worked and I was able to switch to a different window an kill PA. Both times this happend in later game stages, so I suspect some timing/racing going on here. As I was not able to trigger this on an empty planet. Both occasions I was playing GW.
This is main problem of Linux version at moment. Task on bug tracker: PA#2392 Unfortunately there nothing you can do about it.
My instance of this bug was recently fixed. Presubably by the "Linux: Coherent hotfix for BadAccess problem." in 71729
Yup, that's the one. They fixed it, so that the badaccess is handled more gracefully now. So now the whole UI won't go down if something does something bad.
